CHECKERS OR WRECKERS
In my 12v cummins (sig truck) When i start it cold it reads slightly higher than normal oil pressure and when it comes up to temp is reads considerably lower than normal at idle (pressure returns to normal and doesnt move when motor is under load)
By "normal" I mean the spot that it had always sat at rock solid for the whole time i owned it whether under load or at idle until a few weeks ago when it started fluctuating. At its highest and lowest points it is still withing the guages "normal"/ "safe" range. Since it doesnt plummet to 0 or spring off the charts to high i am not too conserned but am curious why all the sudden it would start reading differently. Do you guys think its a guage issue or something actually pressure related?
To knock off the easy ?'s Im running the same oil as always (superlube 15w-40) and same filter. It started right before I last changed the oil and began reading low so i changed the oil thinking it was thinning out faster than usual, but symptoms have continued after the oil change.
